I have a cue with a pretty nasty nick in the butt sleeve's finish. The nick appears to only be in the finish and not deep enough to reach the wood. My question is, Is there a good, easy way to fill this ding and bring the finish "back to life"? I've heard of people using some kind of crazy glue, but I'm not sure of the process. This cue doesn't have much value, so I'm not afraid of experimenting a little, I just need a nudge in the right direction. Thanks
